Per NCERT, what does CONSTANT velocity mean — referenced in Newton's First Law?
AOnly constant speed, direction can change
BOnly constant direction, speed can change
CNo change in either the MAGNITUDE or the DIRECTION of velocity — motion in a straight line at constant speed
DZero velocity always
Answer & Solution
Correct answer: C. No change in either the MAGNITUDE or the DIRECTION of velocity — motion in a straight line at constant speed
Per NCERT §6.4 Note, constant velocity = constant magnitude AND direction. The other options miss one aspect.
